I can only say that if you want to keep fit, you can go to fun run. Although it is not cost-effective, it doesn't matter if you use what you don't need now in advance, but don't divide it into too many installments, which is not cost-effective, especially if the fee is high. If you are financially nervous, sometimes you will spend as much as possible according to your actual situation, and then you choose a better financial management app with low fees to help you repay, and recommend a card return app for you, with low fees.
